Hello everyone! I am studying in Moscow State University, Russia (sorry for crooked english), and now I have to start a project connected with video processing. Due to requirements it must contain interesting algorithms and must be needed to large group of people. So I'm asking you to help me decide what task to choose.
Now in detail: Task must be in video processing area. It will be VirtualDub filter as a result and it will be free to download from here: http://compression.ru/video/ It's desirable for task to be connected with following: stereo, 3d, depth maps, object detection, object tracking.
I will be glad to see any comments. If someone is intrested in development process - I'm ready to contact |

The development of the free filters in that site seems dead, do you have some informations?

No, development is still in progress, at least updating some filters. If you'll give me a great idea there will be absolutley new free filter :) |

An idea => a sort of demosaic filter: - [ QUOTE ] resizing to about 1/4 the orignal pixel distortion before the mosaic, sharpen, blur and then resize to orginal with anti-aliasing and it clears it up a lot [ /QUOTE ] (since this process decrease quality of the entire video it should detect the pixellated part, that can move in the video, and operate only on this part) - Maybe also using "motion compensation for finding corresponding areas in neighbor frames" like this: http://www.infognition.com/articles/what_i...resolution.html - Maybe the filter could also have options to load a set of external images that can help to improve quality of the reconstructed "parts", like some image of faces where the filter detect the most similar compared to the one inside the video and take particulars from it (in case there are censored faces in the video, but it should also adapt to other censored parts)
This idea require tracking of pixelated objects and maybe can be made compatible also to 3d censored videos (if there are) but I'm not sure about it.
PS: There have been several updates to the filtering support in VirtualDub and the MSU filters hadn't been updated for the new features of VirtualDub, also the last update to free filters was probably 2 years ago (also more then 5 years ago for many filters).

Thanks a lot, I'll remember this idea. But it doesn't correlates with 3d and object detection as needed. Let's say I need a project right fom these areas. |

Good thing, do you think that also "MSU Subtitle Remover" will be updated?

Sorry, I don't know exactly. Maybe you should ask in that thread. |

A deshaking application which involves object detection would be a great application. Please consult deshaker as an example which is implemented pretty well. If you need more details, please let me know.
Also, any way to update cartoon restore for new gpu's  Or in general, update some of the filters to utilize new technology? I thought that site was dead for a long time. What is the status of all the other filters in that site? |

Yep, can you tell me in detail what do you want to see?

Developing new gpu versions of some filters is in progress, as I know. I can ask about cartoon restore. |

There is a current filter out there called deshaker which reduces shaking or jitter in video. http://www.guthspot.se/video/deshaker.htm
This filter is well implemented but still has its limitations. First, its a two step process which makes processing multiple files or batch files a pain. Second, the filter has issues with areas of low contrast. Third, the image reconstruction can use some fine tuning.
I would like to see if we can make this technology more robust for instances of low contrast. I believe the current implementation is done with pixel sums to match one area to another based on parameter information. I believe that a second algorithm based on true image recognition would enhance the concept.
The benefit is for everyone since most portable devices have cameras on them. The need to deshake videos is great and a simple application which is more robust would be a great project.
A second concept would be to correct for lens distortion.
Adobe photoshop has this type of filter which corrects for distortions due to say fish eye lenses.
It would be great if they could post some updates to the other filters. I love the work you guys did and continually use the software. What is the best way to contact someone? I have tried the email but none ever answers.
Also, I always wanted to try the super resolution filter which is only available commercially. |

Do you have access to the files? I see a deshaking software but only available for commercial use. Thanks |

I would love to see a program like deshaker which would also minimize or eliminate CMOS wobble. From what I had read about it that might be exceptionally difficult to do and if possible would be another slowdown in the processing. |

Msu already have deshaking software but only for commercial use. I would love to see and test it |

Bump I am really curious about some of these filters, any input would be appreciated.
